REDKEN Extend Blondage Color Depositing Purple Shampoo & Conditioner Set for Blonde & Gray Hair | Tones Brassiness & Enhances Shine | Salon-Quality Hair Care for Color-Treated Locks

The perfect purple shampoo to maintain my blonde highlights. I can’t stand when it’s brassy and yellow. I use it once, maybe twice a week, and it maintains the more toned blonde I am going for. I leave it in for the 3-5 minutes it says after using normal shampoo.
